Patent EP-0402741-A2 (EP)
Inventor: KAMMERL ANTON DR-ING
IPC: H04L69/40
Filed: 1990-06-05
Abstract: For forwarding cells through a switching device, the cells in each case have a cell header, in which control information items required for the forwarding and protection information items associated therewith are contained. Using the protection information items, the relevant switching device carries out an evaluation of the transmitted cells with respect to the occurrence of bit errors in the cell headers. The forwarding of cells which have been identified as faulty with respect to the cell headers is prevented. In the course of the evaluation, an occurrence of a first cell group, comprising a fixed number of directly successive cells which have been identified as being faulty is assessed to be the start of an error bundle. In the event of an error bundle, the forwarding of cells which have been identified as faulty is prevented until the occurrence of a second cell group, comprising a fixed number of directly successive cells which have been identified as being free of errors. The occurrence of the relevant second cell group is assessed as the end of the respective error bundle and the ultimately transmitted cells belonging to the relevant second cell group are forwarded. <IMAGE>

Abstract: Mechanical cellulosic fibrous material pulp (mechanical pulp to produce paper products) having lower freeness, and enhanced light scattering properties, tensile and tear strengths, for a given energy input, is produced by force feeding a refiner (10). Using a progressive compacting plugscrew (12,46,48), cellulosic material (e.g. wood chips) is fed to the refiner inlet (15) at a rate greater than the transporting capacity of the refiner (e.g. about 10-40% greater). The refiner preferably is a low frequency conical refiner with steam removal (22) at the grinding area between the conical refiner elements (18,19). The production rate is regulated by sensing (via 32) the axial force on the refiner rotor and controlling the spacing (21) between the refiner elements (18,19) in response to the sensed axial force. The screw has a compaction ratio of at least 3/1 for wood chips and 6/1 for pulp, and is rotated at about 6-10% the speed of rotation of the refiner rotor.

Abstract: A series-to-parallel converter (26) converts an input code sequence to first to N-th code sequences with input clocks frequency divided by N into circuit clocks, based on which a frame pulse is generated. Among concurrency detectors (41) which are supplied with the frame pulse in common and with detection signals produced when first to N-th synchronization patterns are detected in the respective code sequences and are for producing nonconcurrent results when the detection signals are nonconcurrent with the frame pulse, a particular detector produces an earliest concurrent result to disable other detectors when the frame pulse is concurrent with one of the detection signals that is supplied thereto. These other detectors are enabled when the particular detector produces a nonconcurrent result due to collapse of frame synchronism. Through an AND gate (43), the nonconcurrent results inhibit the circuit clocks.

Abstract: The invention relates to a tape suitable for use in fuel cells, to an electrode suitable for use in a fuel cell, to a method for sintering an electrode of this type and to a fuel cell which contains an electrode of this type. 
     The invention provides a tape with improved properties, which is characterised in that said tape contains LiC 0 0 2 . A tape of this type can be produced in a manner known per se using LiCo0 2  and a binder. Expediently, a plasticiser and/or dispersant and/or anti-foam is used together with the binder, as is known per se for the preparation of tapes. 
     Platelets can be produced from such a tape, which platelets can then be sintered, optionally after stack-ing. Sintering is expediently carried out in an atmosphere consisting of 60 to 80% air and 40 to 20% carbon dioxide, in particular 68 to 72% air and 28 to 32% carbon dioxide. A suitable temperature programme is chosen for sintering. Good results are obtained by heating to 250° C at a heating rate of 100°C per hour, then heating to 450° C at a heating rate of 50° C per hour, then heating at a heating rate of 100°C per hour to the desired sintering temperature of 800 to 1000°C and finally, after sintering, cooling to room temperature at a rate of 100°C per hour. Of course, the invention also relates to fuel cells which are provided with a material according to the invention.
